'BOBERT T. PETTEBONE, OF WYOMING, PENNSYLVANIA.

SHOVEL, SPADE, OR SCOOP.

SPECIFICATION forming part of Letters Patent No. 257,752, dated May 9, 1882,

Application filed January 12, 1882. (ModeL) To allwhom it may concern:

Be it known that I, ROBERT T. PETTEBONE, of Wyoming, in the county of Luzerne and State of Pennsylvania, have invented certain 5 new and useful Improvements in Shovels,

Spades, and Scoops, of which the following is a full, clear, and exact description.

My invention relates to the class of shovels known generally as riveted work, in which the front and back straps are riveted to the blade. The objection is generally made that the back strapprojects from the surface of the blade and obstructs the use of the shovels, be

sides wearing the straps and the rivets, so that I 5 back strap has beencountersuukin a reccss,the ridge thereby formed on the face of the blade is open to the same objection, besides giving an unusual appearance to the shovel.

My invention consists in riveting the back strap within and to the sockets formed in the blade for the handle, thereby preserving the natural shape of the face of the blade and relieving the back from any projection, as hereinafter described and claimed. 7

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

, improved construction. Fig.2 is aback view of the same. Fig. 3 is a cross'section on line at a), and Fig. 4. is a longitudinal section on line y y of Fig. 1.

A is the blade. B is the back strap; 0, the front strap, and D the handle. The blade is formed with araised socket portion, a, of usual form, on the face of which the front strap, 0, is riveted, and at the back of which the strap B 40 is riveted. As shown most clearly in Figs. 3 and, 4., the strap B is shaped to fit the sides of they are liable to come apart, or else, when the Figure 1 is a face view of a shovel of the the socketa, so that the middle portion of such strap forms the back of the socket, while the edges are bent backward as straight flanges, which being riveted to the sides of socket a, instead of to the back of the shovel, the strap lies flush, or nearly so,with the blade. In this manner the strap is saved from wear, there is no projecting edge or ridge on the blade, and, the straps being closed closely to the sides of the handle, perfect rigidity and durability are secured.

The advantages of this construction, stated briefly, are as follows: The blade of the shovel, spade, or scoop presents the same general appearance as all ordinary back-strap goods. There is no projection or recess in front of the blade to catch dirt, and thereby prevent the shovel from clearing itself when working in heavy soil. By there not being any depression, corrugation, or recess near the center of the blade, Iavoid straining the metal and weakening the blade.

I am aware'that back straps of shovels have been countersunk by depression in the blades to prevent wear of the strap. Such method of construction I do not claim.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with a shovel-blade having the handle-socket portion a, of a back strap, B, having its edges bent back, as described, to form straightflanges on the sides of the. socket portion,and rivets passing through said flanges and socket-si des,as and for the purpose specified.
